Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
According to the wet clutch 100 of the embodiment of the present invention, as shown in Figure 1, comprising: initiatively hub 1, driven hub 2, antithesis sheet 3, friction plate 4, piston 5 and elastic component 6.Wherein, initiatively hub 1 has chamber V, and a part for driven hub 2 stretches in chamber V.Antithesis sheet 3 can axially movably be located on the inner circle wall of chamber V, and antithesis sheet 3 is ring, to be enclosed within driven hub 2 and the periphery wall of the inner circle wall of antithesis sheet 3 and driven hub 2 is spaced apart outside antithesis sheet 3, and friction plate 4 is located on the periphery wall of driven hub 2.Piston 5 is located in chamber V movably, and piston 5 is constructed to extrude antithesis sheet 3 and contacts with friction plate 4 to make antithesis sheet 3.Here, the direction of the central axis OO ' being parallel to initiatively hub 1 is axially referred to.Alternatively, antithesis sheet 3 is steel disc.
Particularly, as shown in Figure 1, initiatively hub 1 is provided with housing 11, limits chamber V, be filled with cold oil in chamber V in housing 11, and antithesis sheet 3 and friction plate 4 infiltrate in cold oil, thus cold oil can take away the heat of antithesis sheet 3 and friction plate 4 generation.Advantageously, antithesis sheet 3 is multiple, and friction plate 4 is annular and has multiple, and multiple antithesis sheet 3 and multiple friction plate 4 interval are arranged, and are provided with a friction plate 4 between two adjacent antithesis sheets 3.In the example of fig. 1, antithesis sheet 3 is equal with the quantity of friction plate 4, and wet clutch 100 also comprises platen 7, and platen 7 is fixed on the inner circle wall of chamber V, and the periphery wall of the inner circle wall of platen 7 and driven hub 2 is spaced apart, and platen 7 is for the location of friction plate 4.Specifically, when piston 5 extrudes antithesis sheet 3, antithesis sheet 3 moves vertically and contacts with friction plate 4.Friction plate 4 is also provided with towards the trend of the Direction distortion away from antithesis sheet 3 after being subject to the extruding of antithesis sheet 3, and the setting of platen 7 can only be against on platen 7 after making friction plate 4 stressed, ensure that fully contacting of antithesis sheet 3 and friction plate 4.
More specifically, as shown in Figure 1, the amount of force being positioned at the both sides on its movement direction of piston 5 can the movement of control piston 5, for convenience of describing, all claims the sap cavity away from antithesis sheet 3 side of piston 5 to be piston cavity P in explanation hereafter.In the example of fig. 1, piston 5 is located in chamber V, piston 5 is connected with Sealing 8, and piston 5 and Sealing 8 coordinate to limit piston cavity P with the inner circle wall of chamber V, and piston cavity P is not communicated with other parts of chamber V.Initiatively hub 1 is provided with oil duct L, and the other end of one end connection piston cavity P, the oil duct L of oil duct L is piston oil inlet hole 13.
In wet clutch 100 operation process, initiatively hub 1 moves with motor not stall, and wet clutch 100 is oil-filled to complete joint in piston cavity P by piston oil inlet hole 13.
The engaging process of wet clutch 100 is: when fluid is filled with piston cavity P, and fluid promotes piston 5 and moves towards antithesis sheet 3, and the stressed rear edge of antithesis sheet 3 moves axially towards the direction of friction plate 4, until antithesis sheet 3 and friction plate 4 close contact.Because area of contact between antithesis sheet 3 and friction plate 4 is large, the frictional force produced therebetween is also very large, produces friction torque between antithesis sheet 3 and friction plate 4, thus drives driven hub 2 to rotate.
When wet clutch 100 is separated, piston cavity P inner fluid pressure drop even force value reduces to zero, and piston 5 return gradually under the effect of double side acting power, loosens between antithesis sheet 3 and friction plate 4.
But it should be noted that, when wet clutch 100 is separated, owing to can produce speed discrepancy between antithesis sheet 3 and friction plate 4, oil film between the two can produce corresponding shearing force, and this shearing force is directly proportional to both speed differences, is inversely proportional to both distances.Under the effect of this shearing force, wet clutch 100 can produce certain moment of torsion, is towing moment of torsion.That is, when wet clutch 100 is separated, if towing moment of torsion is comparatively large, then initiatively hub 1 still drives driven hub 2 to rotate, and causes the transmission efficiency of clutch to decline.
For avoiding the traction phenomena of clutch when being separated, the wet clutch 100 of the embodiment of the present invention is also provided with elastic component 6.
With reference to Fig. 1, elastic component 6 be located at antithesis sheet 3 towards on the sidewall of friction plate 4, and elastic component 6 is positioned at the outside of friction plate 4, that is, elastic component 6 and the distance of the central axis OO ' of active hub 1 are greater than the periphery wall of friction plate 4 and the distance of the central axis OO ' of active hub 1.And the axial natural length of elastic component 6 is greater than the axial dimension of friction plate 4, the elasticity of elastic component 6 can play the effect of return spring, and thus, elastic component 6 makes antithesis sheet 3 have from return function.
Specifically, when wet clutch 100 engages, punching oil in piston cavity P, when piston cavity P internal pressure is greater than the elastic force of elastic component 6 on antithesis sheet 3, piston 5 extrudes antithesis sheet 3 and contacts with friction plate 4 to make antithesis sheet 3, and antithesis sheet 3 moves after being squeezed vertically, elastic component 6 on antithesis sheet 3 is only against on the antithesis sheet 3 adjacent with this antithesis sheet 3 or platen 7, the axial dimension of elastic component 6 shortens, the setting of elastic component 6 does not affect the frictional force between antithesis sheet 3 and friction plate 4, produce friction torque between antithesis sheet 3 and friction plate 4 to rotate to drive driven hub 2, thus achieve the joint of wet clutch 100.When wet clutch 100 is separated, piston cavity P internal pressure declines gradually, when piston cavity P internal pressure is less than the elastic force of elastic component 6 on antithesis sheet 3, antithesis sheet 3 by the resilient force return of elastic component 6, piston 5 also return under the promotion of elastic component 6 simultaneously.Wherein, natural length due to elastic component 6 is in the axial direction greater than the size of friction plate 4, and antithesis sheet 3 can move freely after having departed from the extruding of piston 5, therefore when wet clutch 100 is separated, elastic component 6 can resile and promote antithesis sheet 3 and move towards the direction away from corresponding friction plate 4, thus realize antithesis sheet 3 and friction plate 4 rapid, be thoroughly separated, namely achieve the self-return of antithesis sheet 3.
Here it should be noted that, because when wet clutch 100 is separated, antithesis sheet 3 can be separated rapidly, thoroughly with friction plate 4, thus the distance between antithesis sheet 3 and friction plate 4 increases rapidly, this just makes the oil-shear power formed reduce rapidly between the two, the towing moment of torsion of wet clutch 100 also reduces rapidly, namely achieve driven hub 2 when wet clutch 100 carries out lock out operation and can depart from initiatively hub 1 immediately, thus improve the maneuverability of wet clutch 100, also make the transmission efficiency of wet clutch 100 improve.
Because elastic component 6 can realize the self-return of antithesis sheet 3, elastic component 6 instead of the effect of piston return spring, therefore the wet clutch 100 of the embodiment of the present invention can cancel the setting of piston return spring, thus reduces the overall axial length of wet clutch 100.Due to the critical component that clutch is automobile gearbox, the axial length of wet clutch 100 shortens and whole gearbox designs can be made compacter.
According to the wet clutch 100 of the embodiment of the present invention, by the side towards friction plate 4 at antithesis sheet 3, elastic component 6 is set, and the axial natural length of elastic component 6 is greater than the axial dimension of friction plate 4, thus the distance widened rapidly when wet clutch 100 is separated between antithesis sheet 3 and friction plate 4, reduce towing moment of torsion, and then improve maneuverability and the transmission efficiency of wet clutch 100.In addition, because wet clutch 100 can cancel the setting of piston return spring in conventional clutch, therefore the overall axial length of wet clutch 100 shortens, and structure is compacter.
In certain embodiments, as shown in Figure 2, elastic component 6 is multiple, and multiple elastic component 6 is uniformly distributed circumferentially on antithesis sheet 3.Here, circumference refers to the direction of the central axis around antithesis sheet 3.Thus, when wet clutch 100 is separated, antithesis sheet 3 uniform force can be ensured, steadily mobile.
Particularly, as shown in Figure 2, the periphery wall of antithesis sheet 3 is formed as multiple spline tooth 31, and multiple elastic component 6 is located on multiple spline tooth 31 respectively.
That is, the periphery wall of antithesis sheet 3 is formed as spline, here, as shown in Figure 1, the inner circle wall of chamber V is formed with the keyway 12 coordinated with multiple spline tooth 31, keyway 12 extends along the direction of the central axis OO ' being parallel to initiatively hub 1, after the spline tooth 31 of antithesis sheet 3 coordinates with keyway 12, antithesis sheet 3 and can not be rotatably assorted initiatively between hub 1 can be realized, and define antithesis sheet 3 and move along the axial direction of active hub 1.
Here, antithesis sheet 3 by multiple spline tooth 31 and active hub 1 connection for transmission, thus realizes the object that guidance quality is good, centering precision is high, transmitting torque is large, structural reliability is strong.Elastic component 6 is located on spline tooth 31, elastic component 6 and the periphery wall distance of friction plate 4 can be ensured, not easily contact.
Further, as shown in Figure 2, the spline tooth 31 on antithesis sheet 3 is even number, and the quantity of elastic component 6 is the half of the quantity of spline tooth 31.That is, in the circumference of antithesis sheet 3, an elastic component 6 is just set at interval of a spline tooth 31.Because antithesis sheet 3 upper spline tooth 31 is even number, therefore can ensure that elastic component 6 can be uniformly distributed.Here, the quantity of elastic component 6 is the half of spline tooth 31, is the density in order to reduce elastic component 6, ensures that cold oil flows between antithesis sheet 3 and friction plate 4 swimmingly to take away unnecessary heat.
In certain embodiments, as shown in Figures 2 and 3, each elastic component 6 is formed as the sheet between antithesis sheet 3 with acute angle, and alternatively elastic component 6 is membrane-like spring.Thus, elastic component 6 structure is simple, and easy processing, cost is lower.
And for the diaphragm arranged perpendicular to antithesis sheet 3, owing to forming acute angle between flap elastics in the embodiment of the present invention 6 and antithesis sheet 3, elastic component 6 can rotate towards the antithesis sheet 3 being provided with this elastic component 6 after extruding by two adjacent antithesis sheets 3, avoid the plastic deformation of elastic component 6, ensure that the elastic support effect of elastic component 6.
Particularly, as shown in Figures 2 and 3, each elastic component 6 is tilting to extend along the direction away from antithesis sheet 3 on the direction at the center of antithesis sheet 3 from the sidewall of antithesis sheet 3.
Advantageously, as shown in Figure 2, each elastic component 6 is provided with oilhole 61 through on the thickness direction of elastic component 6, thus is convenient to the circulation of cold oil, decreases the loss that cold oil flows through elastic component 6.
Further, elastic component 6 is stamped to form by a part for antithesis sheet 3, thus the structure of wet clutch 100 is compacter, and improve the reliability be connected between elastic component 6 with antithesis sheet 3, avoiding elastic component 6 to mix after antithesis sheet 3 disengaging is clipped between antithesis sheet 3 and friction plate 4, thus avoid the wearing and tearing of elastic component 6 pairs of antithesis sheets 3 and friction plate 4, extend the life-span of wet clutch 100.
In one particular embodiment of the present invention, antithesis sheet 3 is multiple and the axial distribution of edge active hub 1, and each antithesis sheet 3 is provided with multiple elastic component 6.Elastic component 6 on each antithesis sheet 3 is stamped to form by a part for this antithesis sheet 3, and the elastic component 6 on each antithesis sheet 3 is all uniformly distributed circumferentially on this antithesis sheet 3.Wherein, the multiple elastic components 6 on two adjacent antithesis sheets 3 are crisscross arranged.
Such as, in the example shown in Fig. 1 and Fig. 2, the spline tooth 31 on each antithesis sheet 3 is even number, and the quantity of elastic component 6 is the half of the quantity of spline tooth 31.Wet clutch 100 comprises five antithesis sheets 3, and distance platen 7 antithesis sheet 3 is farthest first antithesis sheet, the like, the 5th antithesis pitch of fins tripping dish 7 is nearest.Wherein, first antithesis sheet, the 3rd antithesis sheet are corresponding with the setting position of the multiple elastic components 6 on the 5th antithesis sheet, second antithesis sheet is corresponding with the setting position of the multiple elastic components 6 on the 4th antithesis sheet, and the setting position of multiple elastic components 6 on first antithesis sheet and second antithesis sheet is staggered.
Here, because the part of elastic component 6 by antithesis sheet 3 is stamped to form, namely the part on antithesis sheet 3 cuts rear disengaging remaining part and bends towards the direction away from antithesis sheet 3, like this, to the region of elastic component 6 becoming vacancy section (scheming not shown) on antithesis sheet 3, arrange if first antithesis sheet is corresponding with the multiple elastic components 6 on second antithesis sheet, elastic component 6 then on first antithesis sheet faces the vacancy section on second antithesis sheet 3, elastic component 6 on first antithesis sheet does not reach second antithesis sheet, then elastic component 6 does not have the effect supporting resilience.Therefore, the elastic component 6 on two adjacent antithesis sheets 3 need be interspersed.
In other embodiments of the present invention, each antithesis sheet 3 is provided with an annular elastic component 6, and namely elastic component 6 is formed as the shape being similar to diaphragm spring, and this is just equivalent to add a diaphragm spring between adjacent two antithesis sheets 3.Wherein, the internal diameter size of this elastic component 6 is greater than the outside dimension of corresponding friction plate 4.Here, an annular elastic component 6 is identical with the elastic support effect of above-mentioned multiple elastic components 6 to an antithesis sheet 3 to the elastic support effect of an antithesis sheet 3, repeats no more here.
It should be noted that, concrete structure and the working principle of active hub 1, driven hub 2, friction plate 4 and piston 5 have been well known to those of ordinary skill in the art, will no longer describe in detail here.
According to the wet clutch 100 of the embodiment of the present invention, by arranging multiple elastic component 6 or an annular elastic component 6 on each antithesis sheet 3, thus antithesis sheet 3 is played to the effect of elastic support, make the elastic component 6 when wet clutch 100 is separated can promote corresponding antithesis sheet 3 return, reduce the towing moment of torsion of clutch, improve transmission efficiency, and structure is simple, easily realizes.
